Cubic Zirconia has more characteristics of a diamond than any other gemstone. Although it is made from Zirconium Dioxide, it displays the same radiance and sparkle of a diamond, making them appear extremely similar on first impressions. One of the main benefits of Cubic Zirconia is they display no impurities (which are common in lower grade natural diamonds) and are perfectly clear in colour. Our coloured cubic zirconias are created by adding metal oxides into the production process and produces a brilliant sparkle within the stone.
